1、出現Error: ansible requires a json module, none found!
SSH password:
192.168.24.15 | FAILED >> {
"failed": true,
"msg": "Error: ansible requires a json module, nonefound!",
"parsed": false
}
解決：python版本過低，要不升級python要不就安裝python-simplejson
2、安裝完成後連接客戶端服務器報錯：
FAILED => Using a SSH password insteadof a key is not possible because Host Key checking is enabled and sshpass doesnot support this. Please add this host'sfingerprint to your known_hosts file to manage this host.
解決：在ansible 服務器上使用ssh 登陸下/etc/ansible/hosts 裏面配置的服務器。然後再次使用ansible 去管理就不會報上面的錯誤了！但這樣大批量登陸就麻煩來。因爲默認ansible是使用key驗證的，如果使用密碼登陸的服務器，使用ansible的話，要不修改ansible.cfg配置文件的ask_pass = True給取消註釋，要不就在運行命令時候加上-k，這個意思是-k, --ask-pass ask for SSH password。再修改：host_key_checking= False即可
3、如果客戶端不在know_hosts裏將會報錯
paramiko: The authenticity of host '192.168.24.15'can't be established.
The ssh-rsa key fingerprint is397c139fd4b0d763fcffaee346a4bf6b.
Are you sure you want to continueconnecting (yes/no)?
解決：需要修改ansible.cfg的#host_key_checking= False取消註釋
4、出現FAILED => FAILED: not a valid DSA private key file
解決：需要你在最後添加參數-k
5、openssh升級後無法登錄報錯
PAM unable todlopen(/lib64/security/pam_stack.so): /lib64/security/pam_stack.so: cannot openshared object
file: No such file or directory
解決：sshrpm 升級後會修改/etc/pam.d/sshd 文件。需要升級前備份此文件最後還原即可登錄。
6、pip安裝完成後，運行ansible報錯：
File "/usr/lib64/python2.6/subprocess.py",line 642, in __init__ errread, errwrite)
解決：安裝：yum installopenssh-clients
7、第一次系統初始化運行生成本機ansible用戶key時報錯
failed: [127.0.0.1] =>{"checksum": "f5f2f20fc0774be961fffb951a50023e31abe920","failed": true}
msg: Aborting, target uses selinux butpython bindings (libselinux-python) aren't installed!
FATAL: all hosts have already failed –aborting
解決：# yuminstall libselinux-python -y
8、ansible無法起停tomcat的時候，有兩個點需要關注
（1）環境變量，在startup.sh中添加source /etc/profile
（2）後臺運行，加上nohup &
